Costa's Hummingbird Banded in Rockport, Texas During the 2006 Migration

Notice that the Leucistic Hummingbird is not completely white; the tail feathers have normal coloration on the tips.

This Leucistic Hummingbird is being banded. Also in the picture is a blue box containing the bands that are put on the birds.

This Buff Bellied Hummingbird is drinking nectar during the banding process. The white spot on the head is a drop of paint applied by the banders so they can easily spot the birds in other locations during migration. Banders at one location used one color, banders at other locations used other colors.
